Subject: COZY: Rotisserie - style mount for Cozies Under Construction

Hi All:

Well, I probably spelled rotisserie wrong, but you get the idea.  Has
anyone drawn up plans for a mount that allows you to work on a Cozy
airframe -- preferably with the centersection spar and strakes attached --
that will allow you to pivot the fuselage along the roll axis?  I'd like to
build such a thing (1) to allow me to work on the interior of my airframe a
bit more and (2) to make finishing the bottom of the airframe easier.  I'd
rather flip the fusleage around the roll axis than end-for-end when it
comes time to do the work on the bottom.  If no one has invented such a
doo--dad, I'll try to prototype one and let you know how it comes out.

Many thanks,

Jim Cullen

I have turned mine over twice by rolling rather than looping, using only 3
people to do the job.  I made a 4 legged attachment to the firewall, using
the engine mount bolts to attach it.  It protrudes about a foot aft of the
firewall and ends up as a stub about 3 in long, maybe 3/4 in. diameter with
a large washer welded to it.  This stub is about centered between the bolt
holes.  I hook my hoist to this stub and raise the aft fuse enough for the
strakes to clear as it is rolled over.  I left the nose gear extended and
made a stand on the top of the fuse by bolting 1 in angle iron pieces to the
canard attach points, extending these about 2 foot above the fuselage.
These were x braced sideways and braced back to the shoulder harness anchor
points fore & aft.  A 1x4 across these provided a base to sit the nose on
and hold it solid in the roll axis.  I have some legs attached to the
firewall for the aft to sit on also.  This works pretty good, if you have a
hoist that will lift over 6 ft high.  You will need about that to clear the
strakes.  The fuselage will sit about 45 deg nose down when you do this.  It
looked a bit scary, but not as bad as doing a loop over a couple of saw
horses, my opinion anyway.  I have a 10 ft ceiling in my shop so must push
this out the door to rotate.

If you have a conical engine mount it is easy to flip the airplane over
with the canard and wings removed.  

Make a plate out of 3/4 inch plywood which will bolt to the 4 mount points
of the conical mount.

Purchase a heavy duty eye bolt from your local hardware store and two each
nuts for the bolt.

Make two large washers from 1/4 inch 2024.  The ID of the washer should
match the eye bolt and the OD should be at least five inches.  

With the plywood bolted tightly to the conical mount, place an mark at the
diagonal of the 4 mount points.  Drill a hole for the eye bolt through the
mark.

Place the large washers on each side of the plywood.  Using lock tight on
the nut, run one nut down near the bottom of the threads.  Place large
washer onto eyebolt, and slide through plywood.  Place other large washer
on eye bole.  Using lock tight again, tighten last nut onto eyebolt until
finger tight. Let lock tight cure. 

Now to rotate the aircraft.  Retract the nose landing gear, and place nose
on a large piece of blue foam.  Hook an engine hoist to the eye bolt and
jack the airplane up until it is high enough to clear the strakes when
rotated.  Pivot the airplane on the nose.  It sort of like a top on laying
on its side.  Once upside down place saw horses under the longerons at the
rear, and lower the airplane.  Lift the nose and place another saw horse at
the front of the longerons just aft of the instrument panel.

I have used this set up to flip my Long EZ over many times, and the guy who
showed me this trick used it to flip his Cozy III. One person can do it,
but it is much easier with two.

Paul,
	I like your method of turning the fuselage and would like to add
a trick I learned in the C/P newsletter to turn my long EZ which I was able
to turn by myself but took every ounce in strength I had to tip it over.
so I would suggest two people also.  The only thing I would do different
which I think is easy, is to use a 1" x10" board long enough to span across
the rear of the spar so that the holes for the wing mount are used to
attach three bolts through the 1" x 10" to make it rigid.  Extend the 
board far enough past the spar tip to make a support for it to rest on
when the airplane is rolled over so that the spar doesn't hit the ground.
Worked for me.

I would suggest that instead of 1 x 10 use a 2 x 10, and let the ends project beyond the ends of the 
strakes/spar and rounded ends, to protect the ends if you can't quite get high enough, or the 
unthinkable happens.
